Description

Rapid positioning device for scar reduction surgery Technical Field The invention belongs to the technical field of medical appliances, and particularly relates to a rapid positioning device for a tension reducing scar operation. Background The essential aim of the scar treatment is to gradually shrink obvious scar tissue, reduce or eliminate left marks as far as possible, restore the beautiful appearance and the function of skin, and generate substantial damage to the skin tissue of a patient both caused by trauma and surgical cutting, and the skin has an outward expansion tension which continuously acts on the edge of a wound in the scar forming process, thereby generating traction effect on the wound, causing the wound to be difficult to heal smoothly, and even causing the bad effects of scar hyperplasia, widening, bulge and the like; Therefore, in the scar treatment process, a tension reducing treatment mode is generally adopted as an auxiliary treatment means, and favorable conditions are created for scar healing by reducing skin tension around wounds or scars, so that scar hyperplasia is inhibited, and healing quality is improved; at present, a tension reducing component similar to a band-aid structure is often adopted in tension reducing treatment, and the tension reducing component is adhered to the skin surface of a patient, and the tension reducing component is used for reducing the tension of a scar area; However, the above-mentioned existing tension reducing device has the following drawbacks in practical application: The connecting piece of the existing tension reducing device is usually fixedly connected with the base, the pulling and closing direction is fixed, but the forms of scars are various, and the scar not only has a linearly-oriented scar, but also has an arc-shaped, curve-shaped or irregular form, and for the tension reducing device in the fixed direction, when the trend of the scar is not perpendicular to the tension reducing direction, the tension reducing effect is greatly reduced, and even the scar is possibly deformed or healed poorly due to the improper pulling direction.
